It can be hard to judge the exposure, especially in strong light, so consider using histogram on screen and use the post-shot view with histogram and blinkies to optimise.

Obscure tip for the histogram is that I think the only way to be able to adjust exposure while looking at it, in P mode, is to assign Exposure Comp to the lens ring. Otherwise you have to keep flipping between an EC amount display, and the histogram. One of a few flaws that really grinds my gears, given how good the rest of the UI is. The limit on exposure bracketing is another, not that I ever really _did_ manual, in Photoshop, HDR, but I liked the ability to. With the RX100's built-in HDR, I find I'm using the technique quite a bit with really nice results, and often with +- 4 or 5 stops of bracketing.
